Description

Technical Field

[0001] The utility model provides an automatic magnetic core die-casting device, which relates to the technical field of magnetic core production. Background Art

[0002] A magnetic core is a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical core materials. The production process for a magnetic core primarily involves pulverizing, molding, sintering, grinding, and finishing. Core molding equipment is required to form the core. Powder is first placed into the mold cavity of a mother mold. Then, an upper and lower molds extend into the mold cavity and simultaneously squeeze the powder, forming the core.

[0003] In existing magnetic core die-casting systems, powdered material must be manually placed into the die cavity. After die-casting is complete, the core is ejected by an ejection mechanism and removed by a worker before the next core can be die-cast. This results in low efficiency and is difficult to meet the requirements of automated production lines. Therefore, we propose an automated magnetic core die-casting system. Utility Model Content

[0018] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1 to 3The present invention provides an automated magnetic core die-casting device, comprising a die-casting mechanism, a conveying mechanism disposed below the die-casting mechanism, the conveying mechanism comprising a fixed frame 4 and a conveyor belt 1 disposed inside the fixed frame 4. The conveyor belt 1 is magnetic, and a stepper motor 10 is fixed to the outside of the fixed frame 4 and cooperates with the conveyor belt 1. Specifically, the conveyor belt 1 is driven by the stepper motor 10 to perform intermittent movement. The magnetic conveyor belt 1 can be attached to the magnetic core after it is formed, facilitating demolding of the magnetic core and driving the movement of the magnetic core.

[0020] like Figure 1 、 Figure 3 As shown, further, the die-casting mechanism described in the present invention includes an opening and closing mold assembly, an extrusion assembly and an injection assembly. The opening and closing mold assembly includes a bracket 8 fixed to a fixed frame 4 and a forming template 5 arranged on the inner side of the bracket 8. A hydraulic cylinder 6 is fixed between the forming template 5 and the bracket 8. The forming template 5 is semicircular, and the forming template 5 is provided with a slot 19 on one side and a protrusion 16 matching the slot 19 on the other side. Specifically, the two forming templates 5 can be pushed closer to or away from each other by the hydraulic cylinder 6. When the two forming templates 5 are close to each other, the slot 19 and the protrusion 16 engage with each other, so that the two forming templates 5 are spliced ​​together, and a die-casting mold cavity is formed inside for placing powder.

[0021] like Figure 1 As shown, further, in the present invention, a guide rod 7 is symmetrically fixed to the outer side of the forming template 5, and the guide rod 7 passes through the bracket 8 and is slidably connected to the bracket 8. Specifically, the guide rod 7 guides and limits the movement of the forming template 5, making it more stable and less likely to shake when moving left and right.

[0022] like Figure 1 、 Figure 2 As shown, further, the injection assembly in the present invention includes a powder delivery pipe 2 and a guide cylinder 17 fixed to the side wall of the bracket 8, the powder delivery pipe 2 is slidably placed on the inner side of the guide cylinder 17, and the powder delivery pipe 2 is fixed with a push plate 3, an electric push rod 15 is fixed between the push plate 3 and the bracket 8, and the powder delivery pipe 2 is connected to a powder delivery pump. Specifically, the powder required for the die-cast magnetic core is extracted by the powder delivery pump, and the powder is delivered to the inner side of the forming template 5 through the powder delivery pipe 2. After the powder delivery is completed, the push plate 3 is pushed to the left by the electric push rod 15, thereby driving the powder delivery pipe 2 to move to the left and away from the top of the forming template 5 to avoid obstruction to the subsequent extrusion work. The next time powder needs to be injected, the electric push rod 15 is first started to drive the powder delivery pipe 2 to move to the right and above the forming template 5.

[0023] like Figure 2As shown, further, the extrusion assembly described in the present invention includes a hydraulic cylinder 2 9 fixed to the top of the bracket 8, an upper pressure plate 11 fixed to the telescopic end of the hydraulic cylinder 2 9, a lower pressure plate 14 arranged directly below the upper pressure plate 11, and a spring 13 fixed between the upper pressure plate 11 and the lower pressure plate 14. The edge of the lower pressure plate 14 is fixed with a guide rod 2 12, and the guide rod 2 12 passes through the upper pressure plate 11 upward and is slidably connected to the upper pressure plate 11. Specifically, the hydraulic cylinder 2 9 can drive the upper pressure plate 11 and the lower pressure plate 14 to move up and down. When the lower pressure plate 14 moves downward and presses into the inner side of the forming template 5, the powder can be continuously squeezed to form the magnetic core by die casting. Since the spring 13 is compressed when pressing down, when the upper pressure plate 11 moves upward, the spring 13 gradually recovers, so that the force exerted by the lower pressure plate 14 on the magnetic core is gradually reduced until the lower pressure plate 14 is completely separated from the magnetic core.

[0024] like Figure 2 As shown, further, in the present invention, a support plate 18 is fixedly connected to the inner side of the fixing frame 4, and the support plate 18 is arranged on the inner side of the conveyor belt 1. Specifically, through the arrangement of the support plate 18, when the extrusion assembly extrude the powder downward, the support plate 18 supports the top conveyor belt 1, the powder and the forming template 5, thereby preventing the deformation of the magnetic core caused by insufficient support force of the conveyor belt 1.

[0025] Working principle: Hydraulic cylinder 1 6 is started, driving the forming template 5 to dock and form a die-casting cavity; the powder conveying pump draws the powder into the powder conveying pipe 2 and conveys the powder to the die-casting cavity; hydraulic cylinder 2 9 is started, driving the lower pressure plate 14 to extend into the inner side of the die-casting cavity and continuously squeeze downward to die-cast the magnetic core; hydraulic cylinder 1 6 is started again, driving the forming template 5 to open to both sides to demold the magnetic core, hydraulic cylinder 2 9 is started again, driving the lower pressure plate 14 to move up and away from the magnetic core, the stepper motor 10 drives the conveyor belt 1 to move, moving the magnetic core to the right, so that the next station moves to the die-casting mechanism, completing a die-casting cycle, and then repeating the above actions.

[0026] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
